Wave...bump...it hardly matters when you are sitting on the edge of a fast moving boat.
Hardly matters? Are you saying boaters lives don’t matter? You may find yourself apologizing on national TV. Of course it matters whether it was a wave or a bump or the Loch Ness monster.
I sure hope you realize I’m not serious. I just thought bumps in the water were funny. Sort of like the lake is a motocross course. Enjoy your day.
